چکیده
The gut is constantly exposed to a high antigenic load coming from the diet and commensal bacteria. The Gut-Associated Lymphoid Tissue (GALT) constitutes the most extensive and complex part of the immune system and is capable of efficiently distinguishing invasive pathogens from innocuous antigens. The knowledge of its unique structure consisting on organised tissue, inductor of the immune response (Peyer's patches and mesenteric lymph nodes), and diffused tissue, effector of the immune response (intraepithelial lymphocytes and lamina propria lymphocytes), allow us to understand the development and regulation of the immune response in the gut and how this one can be extended to the rest of the organism.

External human exposure and management immune system in pathogenesis of irritable bowel syndrome
External exposed radiation may play an important role in pathogens of irritable bowel syndrome (IBS), although is thought to arise due to a combination of genetic and environmental factors. The result is dysregulated immune responses due to alteration in the gut microbiota population and the subsequent development of gut inflammation. It has recently been shown that the effect of ioni...

A line of evidence shows that the immune system plays important roles in the pathogenesis of the disease. Two main cytokines directing the immune system are IL-6 and TNF-α which may play a role in the immunopathogenesis of this disease. The present study aimed at investigating the serum lev...

متن کاملApplication of extracellular vesicles in the treatment of inflammatory bowel disease
Introduction: Inflammatory bowel disease(IBD) is caused by genetic, environmental, microbial and immune factors. IBD has two primary forms: Ulcerative colitis and Crohn´s disease. The incidence of IBD has significantly increased over the last few decades. Given that patients have poor response to drug treatments or are resistant to drug therapies, new therapies are needed for gastrointestinal i...
متن کاملAuto-antibodies in Patients with Inflammatory Bowel Disease Unclassified
Background: Inflammatory bowel disease unclassified (IBDU) is considered to be an aberrant immune response with loss of tolerance to many antigens. Objective: This paper tries to address whether there is any value to test for auto-antibodies in such patients. Methods: 60 patients with inflammatory bowel disease unclassified participated in the study. Auto-antibodies to nuclear antigen, intestin...
